James Hoban went on to become one of the new federal city's most respected citizens - he took the city's first census, became a captain of the Washington artillery, and served as a lifetime member of the City Council. He designed and built a number of other federal buildings, leaving a legacy that was "never approached in historical importance by any other single architect in the development of the city".
On the 29th September 1981 James Hoban was honoured by bothe the Irish and American postal services when they jointly issued a commemorative postage stamp. this joint stamp issue with an administration outside Europe was unique in the history of the Irish Post Office. The issue was in a single 18p denomination in Ireland and an 18c denomination in the United States. Both stamps featured the same design, on which artists from the two administrations worked together.
